Abstract
The utility model relates to a heating blanket of a gas steel cylinder. The heating blanket is characterized in that the heating blanket comprises a silicon rubber plate, and a heating sheet and a temperature sensor are arranged in the silicon rubber plate. The advantages of the heating blanket are as follows: 1) the heating efficiency is high, the power density is high, the uniformity is good, and a medium can be kept in a natural convection zone for heat exchange; 2) an overheating turn-off loop is provided, a heating system can cut off power when in overheating due to the arrangement of anexternal control system, and the heating blanket is safe as well as reliable; 3) the heating blanket has wide using range and can meet the requirements of most of liquefied compressed gas steel cylinders for external heat tracing.
Description
Technical field
The utility model relates to a kind of gas cylinder heating blanket, is used to improve the relative evaporation of liquefaction cyclinder gas, satisfies the environment of the big flow gas delivery of terminal demand, belongs to gas cylinder heating blanket technical field.
Background technique
The conveying of liquid gas mainly relies on the evaporation of liquid gas surface liquid phase to realize, and evaporation process is an endothermic process.When environment interior heat amount can't satisfy evaporation institute calorific requirement, tend to occur the feed flow deficiency, phenomenons such as steel cylinder Mechanism of External Condensation of Vapor frosting.The steel cylinder heating mainly is the relative evaporation that improves the inner liquid gas of steel cylinder by extraneous additional heat, increase the efficient of liquid pool boiling in the bottle, while makes medium remain on the natural convection district again as far as possible and the nucleate boiling district carries out heat exchange, avoid entering the film boiling zone and carry out heat exchange, improve the flow of carrying.Traditional way mainly relies on a plurality of steel cylinders to put together supply, such way often still the situation that supply falls short of demand can occur in the big environment the inside of terminal traffic demand, and the drawback of this way maximum to be to be subjected to environmental factor restriction very big, the steel cylinder that just must more renew when the steel cylinder container of being everlasting uses has to a certain degree been wasted in a lot of bottles and has not been obtained vaporized gas.The way that also has some the liquid gas steel cylinder to be heated with water-bath, but this way operating process is loaded down with trivial details, heating function is unstable and thermal loss is very big.
Summary of the invention
The purpose of this utility model provides the high and stable gas cylinder heating equipment of a kind of heating power.
In order to achieve the above object, the technical solution of the utility model has provided a kind of gas cylinder heating blanket, it is characterized in that, comprises silicane rubber plate, is provided with heater band and temperature transducer in silicane rubber plate.
Silicane rubber plate of the present utility model can play following effect: because the wear resistance of silicone rubber and ductility are all very desirable, the protection heater band is not damaged; The serviceability temperature scope of silicone rubber between-60～250 ℃, the thermal property excellence of silicone rubber, can be uniform the heat that produces of heater band; The isolation layer of silicone rubber electric heating panel is composited by silicone rubber and glass fiber cloth usually, has high insulating property, and breakdown voltage can reach 20KV/mm～50KV/mm; Play insulation effect.The utility model has utilized some thermomechanics basic principles of fluid transmission, and main what consider is that relation between pressure, flow, temperature, the material etc. is set up basic framework.
The utility model has the advantages that:
1) efficiency of heating surface height, big, the good uniformity of specific power can make medium remain on the heat exchange of natural convection district;
2) can be equipped with overheated turn-off circuit,, heating system can be cut off the electricity supply when overheated by the external control system setting, safe and reliable;
3) heat demand is accompanied in the outside that can satisfy most liquified compressed gas steel cylinders, and using scope is wide.
Description of drawings
The structural representation of a kind of gas cylinder heating blanket that Fig. 1 provides for the utility model.
Embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figure 1, the structural representation of a kind of gas cylinder heating blanket that provides for the utility model is made up of Spring lock catch 1, silicane rubber plate 2, heater band 3, temperature transducer 4, first tenminal block 5 and second tenminal block 6.
Silicane rubber plate 2 thickness are 4mm, and its inside is structure in the form of sheets, and heater band 3 and temperature transducer 4 are cast in the silicane rubber plate 2.What heater band adopted is the resistive material of flexible alloys thin-film electro (selecting according to flow and container size) of 1～5KW.The resistive material of this flexible alloys thin-film electro is the translucent of a kind of sandwich structure or metal flexible electric heating film that full impregnated is bright, the resistance circuit that main heater members is made for the specific alloy paper tinsel, specific power very high (0.36W/cm2-2.1W/cm2), and uniformity is fine.Because steel cylinder generally is in open environment the inside, the heat hot loss is relatively very big, therefore must select good uniformity, heating material that specific power is big.Heater band connects external equipment by first tenminal block 5.What temperature transducer adopted is PT100 platinum resistor original paper, and it links to each other with the control terminal of outside by second tenminal block 6, and exports 4～20mA analogue signal and give outside control terminal.The temperature-measuring range of this temperature transducer is at-50～450 ℃, and precision is 0.2%, satisfy for the accuracy control over temperature demand fully, and its thermal response time is very short, can obtain the value of reading of temperature quickly and accurately.Be provided with Spring lock catch 1 in the both sides of heater band 3, make that heating blanket and gas cylinder can complete parcels, unlikely coming off.First tenminal block 5 and second tenminal block 6 are quick inserting joint.
Working principle of the present utility model is:
Step 1, heater band 3 are connected with the mains, and need coupling 220V power supply, and the temperature control heating module can also externally be set as required to realize heating and temperature control;
Step 2, that heating blanket is wrapped in gas cylinder is outside and buckle snap close;
Step 3, open the power switch of external control module, the temperature value of required heating is set, the general recommendations heating-up temperature is 40 ℃ (but can not above 50 ℃), and heating blanket promptly begins heating.
